Abstract
Singlet oxygen generation by fullerene and astralen containing surfaces and powders under visible irradiation was studied in water and organic liquids by means of 1Δg state luminescence and chemical scavenger transmittance measurements. The chemical method, pioneered for solid photosensitizers of 102, allowed to measure the singlet oxygen concentration in the aqueous medium down to 108 cm-3. The singlet oxygen sensitizing by the solid-phase fullerene-containing systems was found to be 100 times less effective then by fullerene in solution. The results obtained confirm the applicability of these structures in biology and medicine.
